I need to create a rose diagram for historical directional groundwater flow. Unfortunately our company does not have a software program that does it for you.
I have not done one by hand in oh… forever.
Does anyone have any idea on how to create one by hand?
Convert direction and magnitude to x and y as follows - x - magnitude * sin(direction), y = magnitude*cos(direction). I assume up is the Y axis and direction = 0, the way cartographers use it. Reverse sin and cos if you’re using engineering directions.
thanks!
I did some reading up, and this also helps
